"""Run the main loop's I/O polling function for a period of time.
This is most useful in applications where the UI is being drawn "as
fast as possible", such as games. All pending IDelayedCalls will be called.
The reactor must have been started (via the run() method) prior to any
invocations of this method. It must also be stopped manually after the
last call to this method (via the stop() method). This method is not
re-entrant: you must not call it recursively; in particular, you must
not call it while the reactor is running."""
I'm not sure to understand this:
"The reactor must have been started" and
"you must not call it while the reactor is running"
Thanks and regards Manlio Perillo
